      Product Information:

      The 990-08-50-01-05 is a 990-axis vibration transmitter manufactured by Bently Nevada. It is a two-wire, loop-powered, industrial-grade field monitoring device with integrated proximity sensor functionality.

      The 990-08-50-01-05 transmitter is primarily targeted at original equipment manufacturers (OEMs) of equipment such as centrifugal air compressors, small pumps, motor rooms, or fans. It directly receives raw eddy current signals from nearby probes, converts and adjusts them locally into a standard 4 to 20 mA proportional current signal, and then directly inputs it into a PLC or DCS control system, enabling cost-effective monitoring and alarm protection of the overall vibration trend of the equipment.

      In terms of physical and electrical performance, the 990-08-50-01-05 utilizes a hermetically sealed packaging process, providing excellent resistance to high humidity environments (withstanding condensation operation up to 100% relative humidity). Its frequency response range is very wide, providing excellent signal response in the 5 Hz to 6,000 Hz band, thus enabling precise capture of subtle high-frequency vibrations and anomalies in a variety of high-speed or low-speed rotating machinery.

      The 990-08-50-01-05 vibration transmitter is a 4-20 mA loop-powered device from Bently Nevada designed to simplify the protection of machinery. It integrates a proximity sensor and transmitter into a single module, eliminating the need for expensive dedicated rack-mounted monitoring systems like the Bently Nevada 3500. This transmitter can be directly connected to standard programmable logic controllers (PLCs) or distributed control systems (DCS) for monitoring radial shaft vibration in non-critical or auxiliary equipment.
       
      1.OEM Skid-Mounted Assembly: Original equipment manufacturers (OEMs) can directly integrate this module into the control panels of industrial air compressors, small pumps, and blowers, providing end-users with plug-and-play vibration monitoring capabilities.
      2.Auxiliary Equipment (BOP): Ideal for monitoring critical but non-critical equipment such as cooling tower fans, water pumps, and small electric motors, where a complete 3500 rack-mount system would be prohibitively expensive.
      3.Hazardous process installations: -05 Multi-agency certifications allow this transmitter to be installed in process areas containing explosive gases, commonly found in petrochemical facilities, refineries, and gas metering skids.
